Gurus is an Italian brand, founded in 2012 and headed by Chicco Bellini, that counts the likes of Steve Lukather, Joe Walsh and Adrian Belew among its users. 

The main thrust of the company has been to make new pedals inspired by classic gear such as its Echosex pedals, which replicate the vintage Italian Binson Echorec echoes. 

This ethos is seen here with the Double-Decker MkII, based on vintage Marshall amp sounds with the ‘Jose Mod’. Supplied with their own 12-volt power adaptors, the pedals are robustly built and have a distinctive black glass surface that is backlit when powered up.

Based on a larger, older design, the MkII is a valve-driven overdrive pedal featuring two independent channels with Marshall amp flavour that can be used individually or stacked. 

Jose Arredondo modded amps for EVH, Steve Vai and others, and an aspect of his work is replicated here by each channel having a toggle switch that brings in diode clipping: germanium diodes for Channel 1 and symmetrical LED diodes for the slightly gainier Channel 2. 

Each channel has its own I/O, allowing them to be used as two separate pedals via a loop switcher or in reversed order (using a patch lead) in a mono chain. In default use, though, Channel 1 feeds into Channel 2.

Both channels sound authentically Marshall-like, with great tones ranging from clean-ish to full-on, all nicely aided by Tone and Presence knobs that complement each other perfectly in tweaking the sound to your taste. Bringing in the clipping diodes adds another element, ushering in more crunchy break-up, and both channels in use together can deliver searing lead tones.

This new iteration of the SexyDrive MkII perhaps should have been labelled as a MkIII because it’s lost its battery power capability and has its footswitch in a different position, among other changes. But its core function remains the same – which is to provide transparent amp-like overdrive.

Logically laid out knobs with clear white-on-black graduation markings all around make it easy to dial in tones and recall favourite settings. The top row of knobs offers Bass, Middle and Treble EQ knobs that never get extreme but provide classy tonal options to match the sound to your amp, dial in a little treble or mid-boost, or tighten up the low-end. 

There’s quite a range of gain available, but what is special here is the Balance knob, which blends dry and driven sounds to mix articulation and pick attack in with the dirt. It’s great for enhanced clean tones with just a bit of grit, as well as textures that can give you the sense of playing through two amps at once. This is one of the most practical drive pedals we’ve seen lately.
